Hello, I am a plastic sucker. How to solve the problem that my product is easy to stretch?

New factory? It's best to find a better boot master to do it. Otherwise, the head is big and the lacing phenomenon is varied. Two products are pressed on the mold in the middle. If it is in the corner of the product, it will be a fire rack. The temperature depends on the product. Either find a plastic factory to study for a period of time, or find a good boot master to take. If you have any questions, you can contact me directly. I can help you when I have time.
